Web1.1. Objective The main objective of is to determine the coefficient of permeability of granular soil using the constant head test method. 1.2. Scope Permeability, shear strength and compressibility are the three most important engineering properties when looking at soil. In this experiment, we will focus on how to obtain the coefficient of permeability for … The coefficient of permeability varies with the void ratio as e/sup>/(1+e). For a given soil, the greater the void ratio, the higher the value of the coefficient of permeability. Here 'e' is the void ratio. Based on other concepts it has been established that the permeability of a soil varies as e or e /(1+e). Whatever may be the … See more A number of factors affect the permeability of soils, from particle size, impurities in the water, void ratio, the degree of saturation, and adsorbed water, to entrapped air and organic material. See more 1. Laboratory experiments: 1. Field experiments: See more It was studied by Allen Hazen that the coefficient of permeability (k) of a soil is directly proportional to the square of the particle size (D). Thus permeability of coarse grained soil is very large as compared to that of fine grained soil. The permeability of … See more Soil aeration maintains oxygen levels in the plants' root zone, needed for microbial and root respiration, and important to plant growth. … See more There is great variability in the composition of soil air as plants consume gases and microbial processes release others. Soil air is … See more The presence of fine particulate impurities in a soil can decrease its permeability by progressive clogging of its porosity. See more If the soil is not fully saturated, it contains air pockets. The permeability is reduced due to the presence of air which causes a blockage to the passage of water. Consequently, the permeability of a partially saturated soil is considerably smaller than that of fully … See more
